IMPROVEMENT IN PILES FOR BEAMS.

The Schedule referred to in these Letters Patent and making of the same.

I, JOSEPH STORES, of Trenton, county of Mercer, and State of New Jersey,have invented an Improvement in the manuel' of forming the piles fromwhich These objects I secure by forming that part ot' the' rpile whichis to .form the stem of the finished bar, of

two trough-bars, with their lips turned inward ortoward each other, thusinclosing a rectangular space,

' in which I lay bars of iron of the same widthas'this space, and bindthe whole together by wedges driven between any of the bars, thusvmaking this part of the pile sniciently firm to bear the necessaryhandling.

Upon the part of the pile so formed I lay flangepieces, which may be ot'any convenient form', either tongued, as shown at a., Fig. I of thedrawing, or plain, as at (l, Fig. III.

They may be made in one piece, as shown at a, Fig. I, or may be made upof separate bars, as shown at b c, in the same gure.

As drawn in this case, the same bar c, slightly thickened, is used forthe top of the flange, as for the stem' at c', which facilitates thepreparation of the ironfor the piles.

1f thought desirable,.the edgesof ythe trough-bars used in the stem maybe slightly bent together, and the bars inelosed between them begrooved, s o as to assist in holding the trough-bars together.

In the drawing accompanying this speciliation- Figure I shows a pilesuitable for 'an Ibar;

Figure II, one suitable for a deck-beam; and

Figure I'II, one for a T-bar.

7 Disclaimer.

I do not claim any particular form o f flange-piece, nor any method of'securing the ange-pieces to the body of the pile, either by usinggroovcd or tongued bars and wedges, or otherwise.

Claim.

I claim as my invention- Y The improved pile for the stenl or web of abeam, composed of the two iianged-pieces c c', the anges ot' the onebeing turned toward those of the other, the

lfilling-bars interposed between said flanged pieces and the4 wedges bywhich said anged pieces and the illing-bars are fastened together,substantially in the manner described.
